Any person, generally a female, who performs oral sex on a male and then sloshes the resulting sticky substance around the inside of their cheeks. After about 3 minutes of sloshing, the Dick Slosher has the option to either swallow or spit. If the jizz is spit out, the male is obligated to send the Dick Slosher back to the kitchen to make a bologna sandwich.

Bro 1: Yo dawg I heard you found a Dick Slosher on the corner of Packer Ave and Broad St.

Bro 2: Yeah dude. It kinda sucks though because she never swallows my secretion fluid, and now I don't know what to do with all these bologna sandwiches.
